'Unable to route to these addresses' in WAB Direction Widget in ArcGIS Enterprise

[JingchaoZhou]

Hi Esri Community,

I am using the direction widget in WAB in ArcGIS Enterprise, and we are using our own routing service (NAServer). However, it shows 'Unable to route to these addresses' after clicking 'Get Directions' button. It works sometimes if I enter a different address. I am suspecting if I need to rebuild the network dataset and re-publish the routing service. Can anyone help to trouble shoot? Thank you very much.

Please let me know if you solved this problem and how?

Thank you very much!
